Answer:
x=-1
Step-by-step explanation:
0.5(5−7x)=8−(4x+6)
I do not like working with fractions so I will multiply by 2 on each side
2*0.5(5−7x)=2*8−2(4x+6)
5 -7x = 16 -2( 4x+6)
Distribute
5-7x = 16 -8x -12
Combine like terms
5-7x =4-8x
Add 8x to each side
5 -7x+8x = 4-8x+8x
5+x = 4
Subtract 5 from each side
5-5+x = 4-5
x =-1
I will do 9 only. You can do 11.
Question 9
sin(60) = x/8
sin(60)(8) = x
4•sqrt{3} = x
x^2 + y^2 = 8^2
(4•sqrt{3})^2 + y^2 = 64
16(3) + y^2 = 64
48 + y^2 = 64
y^2 = 64 - 48
y^2 = 16
sqrt{y^2} = sqrt{16}
y = 4
Do 11 the same way.
